> 2. Climate change won't end humanity itself, by all probability, people will be better off in 100 years even if we don't do anything about emissions. Better off in terms of life expectancy, poverty etc
Overall maybe, even if 2 or 3 C more in the average temperature can be hard to bear in summer in some places or require much more energy to cool us, which means that we won't be as adapted to those places as we used to be.
In some spots of the world, tough luck. I would like to see (actually I don't) what happens if the sea rises a few meters. Will the people in the north east of Italy and China build coastal dams and raise river beds or let those regions go underwater and migrate somewhere else? There are certainly some areas of the USA that will go underwater too (Florida? NYC?)
And what if the Gulf Stream really stops and Western Europe gets the same climate of the regions of the USA and Canada at the same latitudes?
I’d like to compare the standard of living for the median person in your hypothetical situation where sea level rises.
In 100 years our technology would be so advanced that people would be much much more prosperous. Ok sure a few cities drown but people move and adapt.
I still hold ground on the fact that people will be more prosperous in 100 years with sea level rising - in the sense that a person would prefer to live then rather than now
